*Disclaimer: This calculator provides an *estimation* based on typical Indian conditions. Actual requirements may vary due to specific local weather patterns, precise shading conditions, panel orientation, system component efficiencies, and individual appliance usage. For accurate sizing, it's always recommended to consult with a professional solar installer or engineer for a site-specific assessment.

How It Works: A Simple, Two-Step Process

This calculator streamlines the process of figuring out your solar requirements. You have two options to get started:

Enter Your Monthly Bill (kWh): This is the most common and simplest method. You just need to find your average monthly electricity consumption from a recent electricity bill [cite: image_21f40b.png].
Calculate from Appliances: If you don’t have a bill handy, you can also input the wattage and daily usage of your primary appliances to get an estimated consumption.

Once you have this, the calculator uses a few key inputs to provide a comprehensive estimate.

Key Inputs for Your Estimate

Average Monthly Electricity Bill (kWh): Your monthly energy consumption is the primary factor in determining the size of your solar system.
Average Peak Sunlight Hours (hours/day): This accounts for the amount of effective sunlight your location receives daily. The more sun, the less solar capacity you need.
Overall System Losses (%): Solar systems are not 100% efficient. This factor accounts for energy loss due to wiring, inverter inefficiency, and other real-world conditions.
Individual Solar Panel Wattage (Wp): This is the power output of a single solar panel, which is a crucial factor in calculating the number of panels you need.
Approximate Area per Panel (sq. feet): Solar panels require a specific amount of space for installation and maintenance. This helps you estimate if you have enough space on your roof for the system.

Understanding the Results

After you click Calculate Solar Needs, the tool instantly provides a breakdown of your requirements :

Avg. Daily Consumption (kWh/day): This is your total energy usage per day.
Daily Generation Needed (kWh/day): This is the amount of electricity your solar system needs to generate daily to cover your consumption.
Required Solar System Size (kWp): This is the total power your solar system needs to have.
Estimated Number of Panels: Based on the system size and individual panel wattage, the calculator gives you the number of panels required.
Approx. Rooftop Area Needed (sq. feet): This helps you understand the physical space required for installation.

This tool simplifies a complex calculation, giving you a clear and actionable starting point for your solar journey.
